Overview

•On 10 Jan 2007, New Products Incorporated (NPI) requested new device proposals

•Design proposals for a desk lamp and B

•Improve safety and functionality of devices

Today’s Agenda• Preface (John Wang)

• Design Proposal

- Desk Lamp (Mark Hendryx)

- Toaster Oven (Joseph Pragas)

• Summary (Hong Yoon Kim)

• Questions

Desk Lamp

• Converts electricity to heat and light

• Heat and light are emitted from a light bulb

• Light bulb and lamp shade provide directional light

• Compact

Acceptability of Desk Lamp

• Cost ~ $20-$30

• Part of everyday use

• Numerous models available

• Abundant survey population

Acceptability of Desk Lamp• Desk Lamp is based on basic engineering principles

– Electric circuits– Heat transfer– Light transmission

• Simply disassembly

• Safe

• Numerous functional problems

Areas for Improvement

• Hard to position the light

• Can’t use light for different purposes

• Unidirectional light only

• Lamp shade and bulb can become extremely hot

• User has to touch the lamp shade

• Brightness of light is harsh on the eyes

Functionality Efficiency

Toaster Oven

• Uses electricity to heat up a heating element – arrangement of coils

• Heat is transferred via radiation, induction and convection to food item

• Heat and time settings are variable

• Food can be cooked to various levels – defrosted to charred

Acceptability of Toaster Oven

• Cost ~ $25

• Part of everyday use

• Numerous models available

• Sufficient survey population

Acceptability of Toaster Oven

• Toaster Oven is based on basic engineering principles – Heat transfer– Electric circuits

• Simply disassembly

• Safe

• Numerous functional problems

Areas for Improvement

• Setup requires numerous tasks

• Creates a lot of grime

• Difficult to clean

• Short life-span

• Entire oven becomes hot when in use

• Heating element can come into contact with the user’s hand

Functionality Safety
